The aim of this study was to assess the construct validity and the reliability of two measurement scores of organizational commitment and job satisfaction, to measure the correlation between the two variables, and to explore the effects of different demographic variables on satisfaction and commitment in a Lebanese context. A total of 298 cases from five major banks were analyzed. Rigorous forward and backward translation procedures have been applied to ensure the relevance of this instrumentation in a different cultural context. Results of exploratory factor analysis, confirmatory factor analysis, simple item-internal consistency estimates, and item intercorrelation analysis provided evidence that both instruments have produced reliable measurement scores with construct validity adequate to measure satisfaction and commitment in the Lebanese context. Results also showed that the constructs of satisfaction and commitment were significantly correlated and that satisfaction was a good predictor of commitment. Demographic analysis, discussion of these results, and suggestions for future research were proposed.
